Design and application of intelligent patrol system based on virtual reality

With the development of society, the size and numbers of large-scale places such as shopping malls and airports continue to expand and the need for security automation increases. Patrol robot is a comprehensive system with environmental awareness, route planning, dynamic decision making, behavior decision making and so on [1]. The existing patrols are mainly inefficient manual patrols and it is a viable solution to make patrol robots achieve regular, fixed patrol or interrupted patrol in a complex environment. As a technology with excellent human-computer interaction, virtual reality can be applied to patrol robots and it can improve efficiency and reliability of patrol task. Based on the modeling of known patrol environment, 3 modules based on C++ programming language, which include virtual display module, registration module based on OpenCV visual library, robot remote control module based on TCP/IP protocol, were developed in the paper. This above 3 modules make the system achieve the remote control function and online patrol function of patrol robot. In addition, the realistic sense of the virtual reality technology and the accuracy of registration technology has been proved been proved by experiments.
